We present numerical computations that reproduce the time reversal experiments of Draeger, Cassereau and Fink (Draeger et al., 1998), where ultrasound elastic waves are time reversed back to their source with a Time Reversal Mirror (TRM) in a fluid adjacent to the solid. We also show numerically that multipathing caused by random inhomogeneities improves the focusing of the back-propagated elas...

Teaching how to program independently of teaching a programming language has been recognized as a worthwhile goal in computer science pedagogy, but many have abandoned the goal as being impossible to achieve in practice. Jackson Structured Programming (JSP) is a well-documented and proven program design method that is independent of any programming language. CASE tools have generally been used ...

the nw-se trending zagros fold and thrust belt extends for about 1,800 km from a location some 300 km se of the east anatolian fault in ne turkey to the strait of hormuz where the north-south trending zendan-minab-palami fault system (zmp) separates the zagros belt from the makran accretionary prism. the ne limit of the zagros belt is marked by the main zagros reverse fault which is rotated abo...

The pink hibiscus mealybug, Maconellicoccus hirsutus (Green) (Hemiptera: Pseudococcidae), is a highly polyphagous pest that invaded Florida in 2002 and has recently been reported from several locations in Louisiana. Although identification of its sex pheromone in 2004 improved monitoring capabilities tremendously, the effectiveness and efficiency of different pheromone trap designs for capturin...

This note adds one celebrated coalition formation game due to Gamson (1961) in the list of applications of the theory of hedonic games explored by Banerjee, Konishi and Somnez (2001) and Bogomolnaia and Jackson (2002). We apply their results to study the original Gamson game and o er extensions both to a multi-dimensional characteristics space and to an in nite number of players. JEL Classi ca...
